## Abstract

A non-contact power supply device of an electronic lock includes a power supply unit and an electronic lock, and the power supply unit is oppositely provided with a power supply member and a power-receiving member. The power supply member is connected with a power source, able to produce a radio-frequency signal, while the power-receiving member can induce and receive the radio-frequency signal to form electronic energy to be supplied to the electronic lock for operation. Thus, the power supply member and the power-receiving member can carry out wireless signal transmission to have electronic energy supplied to the electronic lock for locking and unlocking a door, able to avoid the trouble that the battery unit of a conventional electronic lock must periodically replaced with a new one.

## Claims

### Claim 1

A non-contact power supply device of an electronic lock comprising:
a power supply unit being RFID (radio frequency identification), said power supply unit formed with a power supply terminal and a power-receiving terminal positioned oppositely, said power supply terminal and said power-receiving terminal respectively provided with at least one power supply member and one power-receiving member, a certain gap formed between said power supply member and said power-receiving member, said power supply member connected with a power source and able to produce a radio-frequency signal, said power-receiving member disposed at a location opposite to said power supply member, said power supply terminal having one side provided with a first micro-processing unit, said first micro-processing unit connected with said power supply member, said first micro-processing unit receiving said radio-frequency signal to be mixed with a control signal, said radio-frequency signal and said control signal together transmitted by said power supply member, said power supply terminal having one side set with a server, said server connected with said first micro-processing unit and able to obtain said control signal, said power-receiving terminal disposed with a second micro-processing unit, said second micro-processing unit having one end connected with said power-receiving member, which can induce and receive said radio-frequency signal and said control signal transmitted by said power supply member to form electronic energy; and
an electronic lock installed at one side of said power-receiving terminal and connected with said power-receiving member, electronic lock supplied with power and controlled by said power-receiving member, said electronic lock provided with an electronic unit, said electronic unit connected with another terminal of said second micro-processing unit to enable mixing signals to be processed by said second micro-processing unit and transmitted to said electronic unit for triggering said electronic lock to operate.

### Claim 2 (depends on 1)

The non-contact power supply device of an electronic lock as claimed in claim 1, wherein said power-receiving member is positioned in said electronic lock.

### Claim 3 (depends on 1)

The non-contact power supply device of an electronic lock as claimed in claim 1, wherein a power storage unit is provided at one side of said power-receiving terminal, said power storage unit having one terminal connected with said power-receiving member and another terminal connected with said electronic lock.

### Claim 4 (depends on 3)

The non-contact power supply device of an electronic lock as claimed in claim 3, wherein said power storage unit is a battery unit.

### Claim 5 (depends on 3)

The non-contact power supply device of an electronic lock as claimed in claim 3, wherein said power storage unit is a super capacitor.

### Claim 6 (depends on 1)

The non-contact power supply device of an electronic lock as claimed in claim 1, wherein said power-receiving terminal is positioned at a peripheral edge of a door.

### Claim 7 (depends on 1)

The non-contact power supply device of an electronic lock as claimed in claim 1, wherein said power supply terminal is provided at a peripheral edge of a door frame.
